Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique performance characteristics. With that, we have realized the amplifier circuit of the op-amp and in a similar way, we use the device to design all other application circuits of an op-amp. The NJM4558/4559 integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process. Vout = Vi * (1+R1/R2)įor example: Say R1 = 100, R2 = 10 and Input voltage Vi = 20mV. We have the equation for the output Vo =Input voltage * Gain. Also, the device is powered from a single voltage source of VCC. In the above circuit, the op-amp acts as a Non-Inverting Amplifier (Since the input is given to the Non-inverting terminal of the op-amp) and output is provided as Vo. Now let us take a single op-amp from the available two and construct a simple JRC4588 circuit diagram to explain its aplications. Rise-Time, Overshoot, and Slew-Rate Waveform and Test Circuit. The internal connection diagram of JRC4558 is shown below. The device is popular among hobbyists and engineers for being low cost and good performance.Īs mentioned above JRC4558 is a dual op-amp IC. 0 2 Data Sheet DUAL OPERATIONAL AMPLIFIERS AZ4558 Ordering Information A Z 4558 -, Data.

And IM, I thought the purpose of a TS was to have distortion.not to mention that usually IM is caused by bumping against non-linearities of the circuit, something that occurs on a 4558 orders of magnitude above the hearing frequencies, and.
In addition with two of those op-amps on board, the device can perform two different functions at a time that comes in handy in applications.

Lead dress is GROSSLY larger effect than is the manufacturing tolerances on an IC package like the 4558. For example, these devices can be operated directly from the standard 5V supply used in digital electronics without additional -5V supply. Moreover, the device specifically designed for applications like transducer amplifiers, dc amplification blocks to be implemented more easily in single-supply-voltage systems. JRC4558IC can be used in general purpose op-amp operation circuits like comparator, differential amplification or mathematical operations. Note: Complete Technical Details can be found at the JRC4558 datasheet give at the end of this page.Īlternative Op-Amps: LM158, LM158A, LM358, LM358A, LM2904, LM2904Q, LM4558, LM747 The Non - Inverting Input Pin of Amplifier B The Non - Inverting Input Pin of Amplifier A The high voltage gain (100 dB typ.), good input impedance (5 MΩ typ.) and versatile power supply (± 4 to 18 Volts) make it perfect to fit in pedal circuit designs. JRC4558 internally compensated and constructed on a single silicon chip. But again remember that modern Op-Amps like OPA2134 will consume 2-4 times more current than RC4558.The JRC4558 is a high performance monolithic dual operational amplifier. They are less priced and consume very low current but are reported to have some jitters (slow and sloppy) when it comes to quality.
Also since the IC has same properties as LM741 all the circuits with LM741 can be replaced with a RC4558.īe advised that the 4558 Op-Amps belongs to the old 1485 Op-Amp series and does not have great specs compared to modern Op-Amps. You can also find some Geiger counter circuits and Audio amplifier or comparator circuits based on this IC. Because of these characteristics these ICs are commonly found inside DVD players and Guitar amplifiers. Hence requires minimum number of components to be application ready. It also has internal frequency compensation and short circuit protection in-built which ensures stability without external components.
The high common-mode input voltage range and the absence of latch-up make this amplifier ideal for voltage-follower applications. It has a high common mode Input voltage of ☑4V hence the inverting and non-inverting pins can be driven upto this voltage provided they are less than the operating voltage.
(The A4558 is a monolithic Integrated Circuit designed for dual operational amplifier. The RC4558 is a dual package version of the commonly used LM741 Op-Amp, with each half electrically similar to the LM741 except for that there is no offset and null option in the RC4558 Op-Amp. 4558 datasheet, 4558 pdf, 4558 data sheet, datasheet, data sheet, pdf.
